Difference between txv and exv.
Compressor, Condenser, Meter Device and Evaporator
oppisite side of txv sensing bulb on outlet of evaporator (suction line)
The capacity of a TXV differs due to orifice size, pressure difference between high and low side, and the temperature and condition of the refrigerant in the liquid line.

No, it is not.
Dual port TXV used when system need a large TXV for short periods of time. Dual-port valves have two independent capacities larger port for periods of high load smaller port for periods of normal load TXV capacity is doubled when larger port is open all the way.
If it's a TXV system, it'll be located between the receiver-drier and the evaporator.

Are you sure it has a fixed orifice tube system? Most heavy duty trucks use a Thermal Expansion Valve (TXV) system. In both systems, the metering device (orifice tube or TXV) is located between the condenser outlet and the evaporator inlet.
The TXV will be located on low pressure side somewhere between compressor and condensor You need to recover the frion from system before servicing the TXV Tip: The compressor is belt driven off the engine and has 2 hoses leadind to it
